Comment
; Position without punch initiation.
; Activate nibbling, initiate a stroke before the mo-
tion (X=50) and on completion of the programmed move-
ment (X=100).
Comment
; Position without punch initiation, activate delayed
punch initiation.
; Activate punching. The punch stroke is output with
a delay when the end position is reached.
; Deactivate punching with delay, normal punch ini-
tiation on completion of the programmed movement.
Comment
; At the end of the block, a stroke is initiated at
the first fast output. The "Stroke active" signal is
monitored at the first input.
; The second stroke is initiated at the second fast
output. The "Stroke active" signal is monitored at
the second input.
; All further strokes are controlled with the first
interface.
